I'm using Apache 2.4 and php 7.0 configured as module and HttpFoundation 3.0.9. I've read https://github.com/symfony/symfony-docs/pull/2529/files#r3886789 and added the RewriteRule although not running PHP through CGI. When calling app with a `Authorization: Bearer ....` header, it's not available via `headers()`. It is however visible via `apache_request_headers()`. Why isn't Symfony picking up the apache header?
